As a result ,all domain nodes’ properties have to be described by function , results and outputs.
According to the variable’s related properties, and by searching fault mode libraries, variable failure modes are generated.
According to the properties of the variable nEx1553Cmd, we can determine the failure modes.
For example, nEx1553Cmd will check out all the failure mode of type int and according to the properties of M, failure mode can be determined .

The turbocharger in the application affecting the normal work of the diesel engine, or even cause the machine broken fault for multiple failures including floating bearing burning loss, rotor carbon deposition firmly dying leading to be fixed (oil seal leaking) and nozzle ring thermal fatigue cracking, deformation of the blade, etc..
Besides unbalance interior pressures of intensifier, the reason for the oil leak relates to appropriate engine oil quantity of seal structure design, oil return unobstructed and other factors. 1.1 Typical structure of turbocharger oil seal and its problems The specific type of diesel engine turbocharger oil seal structure can be divided into two categories of contact and non-contact type according to their function.
As far as possible to keep the oil return chamber pressure stability and reduce the oil return chamber pressure, which is the advantageous factors preventing oil seal leak.
At the same time, the reliability of the oil return threads at high speed and good dynamic sealing property improve the sealing effect of the oil seal structure and reliability.

Because of the complexity of the process of grinding, the parameters of the camshaft grinding are affected by a lot of factors, such as the size of the camshaft, the cam base circle diameter, the cam surface roughness, the precision, the grinding allowance, the size of grinding wheel, the type of grinding wheel, the depth of grinding wheel dressing, the intervals of dressing and the type of coolant, and so on.
In order to improve the pertinence of the experiments, the spans of 8 experimental factors are appropriately enlarged on the basis of the earlier empirical data.
The table is 6 levels for each of the 8 factors and contains 60 samples. 54 samples are randomly selected to train the network and the remaining 6 samples are selected to test the network.
The properties of the camshaft to be processed are shown in Table 1.

Landslide emergency treatment refers to the engineering technology which makes the landslide deformation under control by taking effective mechanical control measure before sliding.
While the landslide now has been in the limit equilibrium state, which is very sensitive to external factors; mechanical control measures, such as earth-retaining walls and anti-slide piles, with the disadvantages of mass excavation volume, low construction speed and great interference to the slope, is not conducive to seize the preemptive opportunities of landslide emergency management, to protect the stable and keep the landslide from sliding and temporality protect the major facilities or houses.
Hence micro steel pipe pile may after all be accepted as a productive mechanical control measure to, which is simple and easy to carry out and economic and reliable.
Which affect the stability of the landslide is the pore water, a kind of groundwater existing in the slop eluvial deposit silty clays during artificial fill in the Quaternary System.
Emergency rescue means emergency treatment engineering technologies in order to quickly take control of landslide, by changing the mechanical conditions of the slope and keeping the slope from further deformation to protect the stable and keep the landslide from sliding.

As one of severe plastic deformation processes, ECAP can improve materials’ mechanical properties by grain refinement [4, 5], and a large number of studies were carried out to identify it [6-8].
Since the strain and deformation homogeneity of the material directly affect its grain refinement during ECAP, and also the mechanical properties, it has important significance to improve process conditions of ECAP.
The isometric crystals which are small and have excellent mechanical properties are formed at the grain boundary because of dynamic recrystallization.

Parameters in CGDS Process It is widely accepted that impact velocity and critical velocity of the particle are the dominating factors in the CGDS process.
As a factor of great significance in CGDS, the critical velocity is affected by other parameters involved.
Helium and nitrogen are commonly used as the gas propellant in CGDS, instead of pure air because of their nonreactive and thermal properties.
